The early Vulcan 2000's (04 anyways) are notoriously rich from the factory.you dont need a fuel managment system. it wouldnt be a bad idea to get one tho. i added a PCIII to my bike only for peace of mind to richen the mixture a bit. the bikes come alittle lean from factory to pass EPA laws
IMO, unless you are planning on adding an aftermarket airkit as well, i wouldn't bother with the Cobra FI2000.I was looking at: Kawasaki Vulcan 900 Classi Cobra Fi2000R Fuel Processor - (eBay item 270187006694 end time Nov-23-07 13:58:12 PST)
...is this what I need if I purchase new Cobra Dragsters?
